 # Changelog
 
+## 2026-03-05 - 4.1.23 - fix(mod_unpack)
+handle partial readdirSync results when moving nested directory entries and add diagnostic log
+
+- Loop over readdirSync results until the nested directory is empty to avoid missing entries from partial reads
+- Count moved entries and print a diagnostic message with the final destination entry count
+- Keep removal of the now-empty nested directory (fs.rmdirSync) after moving contents
+
+## 2026-03-05 - 4.1.22 - fix(mod_compiler)
+improve logging of successful output directories to include a sorted list of entries and use a shortened relative path
+
+- Adds shortDir variable to display relative path instead of repeating inline replace(this.cwd + '/')
+- Appends a sorted, comma-separated list of directory entries to the log output for easier inspection
+- Change located in ts/mod_compiler/classes.tscompiler.ts
+
+## 2026-03-05 - 4.1.21 - fix(compiler)
+log emitted files written outside expected destination directory for diagnostics
+
+- Adds diagnostic logging for emitted files that are not under the configured destDir, listing up to 20 example paths and reporting the remaining count.
+- Logging is conditional: only when not in quiet mode and not emitting JSON.
+- Diagnostic runs after compilation (post-compile) and before unpacking of outputs; paths are trimmed using the process cwd for readability.
+
+## 2026-03-05 - 4.1.20 - fix(mod_compiler)
+add diagnostic snapshots for output directories around clear and compile steps
+
+- Introduce diagSnap helper to log entry and directory counts for successful output directories when not in quiet or JSON mode
+- Call diagSnap before clearing the destination directory, after clearing, and after compilation to aid debugging of missing or unexpected outputs
+- Behavior for emitted files and unpacking is unchanged; this is observational/logging-only instrumentation
+
+## 2026-03-05 - 4.1.19 - fix(mod_fs)
+use synchronous rm to avoid XFS metadata corruption when removing directories
+
+- Replaced async fs.promises.rm with synchronous fs.rmSync in removeDirectory to avoid observed XFS metadata corruption affecting sibling entries under libuv thread-pool and signal pressure
+- Retains previous options: recursive, force, maxRetries, retryDelay
+- Adds inline comment documenting the rationale for using a synchronous removal
+
+## 2026-03-05 - 4.1.18 - fix(mod_compiler)
+add diagnostic logging of output directory states after compilation and after import-path rewriting to aid debugging
+
+- Imported fs to allow reading output directories for diagnostics
+- Logs entries and directory counts for each successful output directory both pre- and post-import-path-rewrite
+- Diagnostics are gated by !isQuiet && !isJson and are read-only (no behavior change)
+- Tags used: 'diag' (post-compilation) and 'diag-post-rewrite' (after rewriting) to help identify missing or unexpected output folders
+
+## 2026-03-05 - 4.1.17 - fix(tsunpacker)
+use synchronous fs operations in tsunpacker to avoid readdir race conditions
+
+- Replaced async fs.promises.readdir/rename/rm/rmdir loops with fs.readdirSync/renameSync/rmSync/rmdirSync
+- Removed readdir retry loops that attempted to handle partial/stale readdir results
+- Updated comment to document rationale: avoid race conditions under signal pressure and XFS metadata lag
+- Note: function remains async but now performs blocking sync filesystem calls which may block the event loop during unpack
+
+## 2026-03-05 - 4.1.16 - fix(mod_unpack)
+handle partial readdir results from signal-interrupted getdents64 when unpacking to ensure sibling removal and nested moves complete
+
+- Loop readdir calls for destination directory until only the source folder remains to avoid partial-listing leftovers
+- Loop readdir calls for nested directory and repeatedly rename entries until the nested directory is empty
+- Prevents leftover files and incomplete moves when readdir returns partial results under signals
+
+## 2026-03-05 - 4.1.15 - fix(mod_unpack)
+flatten nested output directory without temporary rename steps to avoid race conditions
+
+- Replace rename-rm-rename strategy with: remove sibling entries in destination, move nested source entries up into the destination, then remove the now-empty nested folder.
+- Avoid creating temporary sibling directories and avoid removing the destination directory to reduce filesystem race conditions and metadata lag issues (XFS/NFS/etc.).
+- Remove removed removeEmptyDirectory helper and stop using FsHelpers.move/removeDirectory in unpack; import and use fs.promises methods (readdir, rm, rename, rmdir) directly.
+
+## 2026-03-05 - 4.1.14 - fix(fs)
+replace execSync and fsync workarounds with atomic async FsHelpers operations to avoid XFS races and shell dependencies
+
+- Removed child_process.execSync usage and shell mv/rm commands in mod_unpack and mod_compiler.
+- Removed syncDirectoryTree and fsync-based workaround from the compiler module.
+- Use FsHelpers.move and FsHelpers.removeDirectory (async rename/remove) for atomic filesystem operations during unpack.
+- Await performUnpack directly and simplify unpack flow to improve portability and reliability on XFS and other filesystems.
+
+## 2026-03-05 - 4.1.13 - fix(mod_unpack)
+Use child_process.execSync (mv/rm) to perform unpack atomically, replacing async fs operations and logs to avoid ENOENT/partial directory listings on XFS
+
+- Replaced async fs.promises.rename/rm and readdir/stat debugging with execSync rm -rf and mv operations for sequential, atomic moves
+- Imported execSync from child_process and removed verbose console logging and extra fs checks
+- Addresses race conditions observed on filesystems like XFS where libuv async operations can return partial results or ENOENT errors
+
+## 2026-03-05 - 4.1.12 - fix(mod_compiler)
+replace runtime require calls with top-level imports and use execSync/path.join for filesystem sync and traversal
+
+- Added top-level imports: path and execSync from child_process
+- Replaced require('child_process').execSync('sync') with execSync('sync') to force fs sync
+- Replaced require('path').join(...) with path.join(...) when recursing directories
+- Refactor is purely local/maintenance-focused (consistency and slight performance/readability improvement); no functional change expected
+
+## 2026-03-05 - 4.1.11 - fix(mod_compiler)
+flush directory entries before unpack to avoid XFS delayed-log causing partial readdir results
+
+- Add fs import and call child_process.execSync('sync') before unpacking compiled output to force kernel-level sync
+- Add syncDirectoryTree(dir) to recursively open and fsync directory file descriptors and traverse subdirectories
+- Call syncDirectoryTree on the destination directory before performing unpack to ensure TypeScript writeFileSync entries are committed (prevents partial readdir results on XFS)
+- Errors during directory sync are ignored to avoid breaking normal flow
+
+## 2026-03-05 - 4.1.10 - fix(unpack)
+use atomic renames to flatten nested output and make unpacking more reliable
+
+- Replace per-entry moves with an atomic 3-step strategy: rename nested dir to a temp location, remove the destination dir, then rename temp back to the destination to avoid partial readdir/move under signal pressure.
+- FsHelpers.move switched from sync rename to fs.promises.rename to work with async flows.
+- Use fs.promises.rm with retries and explicit temp-dir cleanup to handle previous failed runs.
+- Add diagnostic logging and verification of intermediate states.
+- Removed the older removeSiblingDirectories and moveNestedContentsUp methods in favor of the new rename-based approach.
+
 ## 2026-03-05 - 4.1.9 - fix(fs)
 improve filesystem helpers: use sync rename for reliability on certain filesystems; retry rmdir with delays and avoid recursive rm; bump @push.rocks/smartfs to ^1.3.2
